From: Erwan Yvin <erwan.yvin at stericsson.com> This driver depends on Rusty's new host virtio ring implementation, so this patch-set is based on the vringh branch in Rusty's git. with the vringh wrapper patch on top. They do not apply cleanly on top of the remoteproc virtio config patches from Sjur, but it merges fine. CAIF will use this new host virtio ring implementation. Ido,
